Pin Functions

PIN I/O DESCRIPTION
NAME NO. VOLTAGE INVERTER VOLTAGE DOUBLER
CAP+ 2 Power Connect this pin to the positive terminal of charge-pump capacitor. Same as inverter
CAP– 4 Power Connect this pin to the negative terminal of charge-pump capacitor. Same as inverter
FC 1 Input Frequency control for internal oscillator:
FC = open, ƒOSC = 10 kHz (typical);
FC = V+, ƒOSC = 80 kHz (typical);
FC has no effect when OSC pin is driven externally		 Same as inverter
GND 3 Ground Power supply ground input. Power supply positive voltage input
LV 6 Input Low-voltage operation input. Tie LV to GND when input voltage is less than 3.5 V. Above 3.5 V, LV can be connected to GND or left open. When driving OSC with an external clock, LV must be connected to GND. LV must be tied to OUT.
OSC 7 Input Oscillator control input. OSC is connected to an internal 15-pF capacitor. An external capacitor can be connected to slow the oscillator. Also, an external clock can be used to drive OSC. Same as inverter except that OSC cannot be driven by an external clock
OUT 5 Power Negative voltage output Positive supply ground input
V+ 8 Power Power supply positive voltage input Positive voltage output
